Abstract

Various embodiments include an apparatus and a method to secure protected digital document content from tampering by their user, such as unauthenticated use or use violating a policy of the digital document. The digital document file can be transferred from a network node such as a web site server to a digital appliance, such as a computer, in encrypted form. The digital document file can be resident already on a device, and/or be transferred into a device that is connected to the digital appliance. The device (hereafter a DRM device) can internally store the digital document or part of the document. The DRM device may decrypt the digital document when requested to do so. The device may further format the content for usage, for example, convert text into its graphic bitmap representation. Device formatting can include sending plain text data to the digital appliance. The device may further process degradation to the resulted file, for example, reduce the resolution of the graphic representation. The digital appliance uploads the result of the processing or sections of the result of the processing for user access via the digital appliance.
